fuel line

[Rob Kuder]

Hi all, I just pulled the bike out of the shed, checked everything over, put the tank back on and filled it with gas. She won't idle. A little bit of throttle will hold 1500 rpm and up. If I use any choke, even at 3000rpm it will die imediately. It only starts with the throttle wide open and reluctantly at that. But it seems to run fine otherwise. Where do I start looking? I only have to cover about 500ft of wet ice to get to dry pavement and it's a balmy 55F, so as you can imagine, I really need to fix this now! Thanks for any help. I don't know carb's, just diesels! Rob.

List wisdom would indicate bad gas. Drain the float bowl. Maybe even put new gas into your tank. Or gas drying treatment. Did you clean the air filter ? I always over oil my K&N and have issues until I baby her up to 65 or 70 mph on the highway for 5-10 miles. Hard start. won't idle; stumble at ~3800 etc.

Thanks all. General wisdom says clogged carb I had the tank off and oiled for the winter with the carb drained. I think the problem was oil in the carb, probably not diluted enough with gas when I refilled the tank. I took the bike out for a tear and the problem cleared in a few minutes. So I rode around for a couple of hours just to make sure it was OK.

When I start my 1999 KLR650 it just turns over and over without starting. If I open up the throttle half way when turning it over it will start and run very rough but only if I keep it at around 4000 rpm. If I drop below that it dies immediately and if I try to put it in gear and go anywhere it also dies immediately. It was running "fine" yesterday but when I got back from my hike it started doing the stuff above and I had to have it towed home. Any suggestions? -ben kirkland, wa __________________________________________________ Do you Yahoo!? Yahoo! Tax Center - File online, calculators, forms, and more http://tax.yahoo.com

Dirt in the carb, clogging pilot jet. You need to pull the carb and clean it with carb cleaner and compressed air. Devon Ben Wiseley wrote:

Glenn- The bike runs like a bat outta hell, just won't idle without the choke on. With the choke on it fires right up. I've ridden it around with the choke on and with it off and it runs great. With it off, even if you try to hold the idle at about 1000 rpm it's pretty rough though. I've cleaned the carb thouroghly, soaked it, blown it out, no parts left over, started the pilot at two turns out, tried less and more with virtually no effect. New hose to petcock diaphragm, rebuilt petcock, (petcock diaphragm seems intact, even if it wasn't, I've plugged that hose and there's no change) new plug gapped at .032, old plug looked like some gas had gotten up on the threads and laquered up, but it runs axactly the same with the new plug... Air filter is clean... What timing issues might I have?? I have a Factory Service Manual coming, but until it gets here you guys are it. : ) I tend to think it's not timing though, just because it ran fine before it sat... ~Eric S.

Somebody must have said this already, but it sure sounds like a blocked pilot jet. Either that or water in the float bowl.

I can guarentee no water... and I can blow through the pilot circuit with ease... so to me it seems clear...(?) ~Eric

Okay, let me try this again as my reply was lost. If your bike will not idle without choke and it runs fine at higher RPM you have a fuel delivery problem. This could be caused by either blockage in the pilot circuit or a kinked/melted carb vent tube. Check the clearish pink tube which connects to the carb that goes down along the shock for any kinks or obstructions. Remove the pilot screw completely and spray a generous amount of carb cleaner in there and then re-install the screw. Tighten the screw until you feel it start to seat, do-not tighten it. Turn the screw back out 2.5 turns total and the bike should run. If the bike has been sitting a while (you did not specify) top up the tank with fresh gasoline and put in a bottle of heet water remover. There aren't many thing that will prevent the bike from idling, and when you clean out the carburetor make sure to use good carburetor cleaner, not WD-40, it's not carb cleaner it's a lubricant. Carb cleaner will break up any dirt inside the carb and it will blow it right out because it comes out at a high velocity. Glenn (Texas) http://www.KLR650.NET

Well, I can assure you it's not a blocked vent tube... it doesn't have one. the port is wide open. Now correct me (or slap me) if I'm wrong, but I wouldn't think that the absence of the hose would cause it not to idle... The carb has been reduced to its basic parts and soaked in real carb cleaner and blown out. I can blow through the pilot circuit with my mouth. I have set the pilot screw at two turns out, and at three turns out. Either way, I can turn the thumb screw on the throttle linkage ALL THE WAY IN and still be 1/16" away from getting it to idle. ~Eric S.
